Title: Method for cleaning hole walls to be provided with a metal layer
IPC: C08J7/12
Filed: 1975-11-05
Abstract: Perforated plastic printed circuit boards having metallised hole walls are produced. Before the metallisation, the hole walls must be freed from resin deposits produced during drilling of the holes. This is performed using alkaline permanganate solution. The solution has a pH-value of at least 13 and a temperature of between 35 and 70 DEG C. In trials, a weight loss was firstly established in connection with the action of such a solution, followed surprisingly by a weight increase and thereupon once again by a weight loss. The treatment of the hole walls with the permanganate solution is terminated before the occurrence of the second weight loss phase. With printed circuit boards which have printed conductors made from insulated wire and cut through by the perforation, the insulation of the wire ends present at the hole walls can be removed simultaneously by the permanganate solution. The exposed wire ends are firmly connected to the metallisation layer during metallisation of the hole walls.

An adjusting screw 13 in the abutment 12c provides compensation for wheel wear. In a second embodiment, Fig.3 (not shown) a spin extending transversely through the lower end of the plunger 8 is engageable in a transverse slot in the lower end of the stem 7 to provide means for a positive swivel lock independently of the wheel brake operation, and a pin extending through the upper end of the plunger 8 is in permanant non-rotatable engagement with a slot in the vertical peg 4a. Alternative fixing screw holes in the peg 4a permits the castor, when the swivel lock is operative, to be set in either of two positions to give fixed tracking movement either across or longitudinally of an article to which the castor may be fitted. The cam 11 gives three operative plunger positions, an upper position in which the swivel lock is operative to give a fixed castor, an intermediate position in which the swivel lock is inoperative and the fork is free to swivel and the wheel is free to rotate, and a lower position in which both the wheel and the fork are braked. The cam may be actuated by a foot-operated pedal or a lever; one foot pedal may be operatively connected to two castors.
